摘要
以毕节市为例,采用地震概率分析方法,对不同地震预防水准的场地进行了持续时间的计算,通过能量持时定义和经验预测方程对地震动与设防水准建立联系,并得出计算结果。结果表明,地震动持续时间与设防标准呈现负及相关,根据负相关的关系方程的建立能够预测地震动持续时间与场地设防标准的对应关系,具有实践意义。
Taking Bijie city as an example, the seismic probability analysis method was used to calculate the duration of different seismic prevention level. The results showed that the duration of earthquake is negative correlated with the prevention level. It could improve the prediction of ground motion duration.
